Key Points
Specimens with 20% fiber and Type-I orientation achieved the highest tensile modulus of 20.71 GPa and strength of 191.50 MPa, outperforming others.
Type-II specimens showed the lowest flexural modulus and strength, with values of 2.32 GPa and 60.03 MPa, indicating orientation's critical role.
Using towpreg coextrusion technology, mechanical properties of 3D-printed composites were assessed under uniaxial tensile and flexural loadings to maximize performance.
Findings support optimizing fiber volume and orientation during the 3D printing process for enhanced composite performance.
